2023 Kia Seltos problems

“My 2024 Kia Seltos, with approximately 50,000 miles, experienced a sudden shutdown while traveling at highway speed, cannot accelerate. The dashboard warning appeared as no key not detected and the brake pedal became extremely hard, making the vehicle difficult to stop. The vehicle subsequently restarted normally. This is a serious safety concern. I am requesting a thorough investigation into the cause of the shutdown, including the main electrical system, power distribution, engine controls, and brake-assist system. Please document this as a highway-speed shutdown with loss of normal braking assistance and provide a written diagnostic report before releasing the vehicle.”

“To the National Highway Traffic Safety Administration (NHTSA), I am writing to formally submit a safety complaint regarding my 2023 Kia Seltos, which exhibits a recurring, dangerous defect involving the engine stalling without warning. This defect results in a total loss of power while the vehicle is in operation or attempting to accelerate, posing a critical safety risk. The failure manifests in two primary scenarios: * **Remote Start Failure:** The vehicle frequently stalls immediately after utilizing the remote start feature when shifting into drive. * **Auto Start/Stop Instability:** The Auto Start/Stop system contributes to the engine shutting down unexpectedly when lifting off the brake or attempting to accelerate from a stop. When this occurs, the dashboard illuminates multiple warning lights (e.g., battery, oil, "key not in vehicle"), and the vehicle loses all forward propulsion. On inclines, this defect causes the vehicle to roll backward, forcing the driver to rely solely on emergency braking to prevent a collision. ### Evidence of Widespread Concern My research indicates this is not an isolated incident; numerous Kia owners report identical,…”

“On 4 different occasions my vehicle applied the brakes forcefully on its own at high speeds. The dash flashed with the message "check forward collision avoidance assist system." as well as displayed the following icons: master warning light, hill climb assist, traction control, forward collision, and the Auto start/stop was flashing. These continued until I was able to stop and turn the car off. When I was trying to slow down and stop my brakes were not working correctly as I had to push the pedal all the way to the floor for a long period to stop all the way. When the car was put in park the engine was revving up until it was off. The car was towed to the dealership after first incident and the following codes were in the history: C164202 C161308. Dealership had my car for 6 days, opened a tech line case and without an answer of why this happened nor remedy, my car was released back to me resulting in 3 additional instances. It is now going to another dealership to hopefully get an answer and repair.”

“Driving 65mph on [XXX] and all the lights came on flashing and alerting me causing the emergency braking to occur while driving causing me to swerve on the road and lucky I didn’t crash but i had my [XXX] old in the car and it scared the hell out of me, on top of all that my horn gave out and hasn’t worked since that incident and now all the lights are off and I don’t even get the beeping for coming to close to another car anymore it’s like I lost all safety features plan to sell the car because I’m not dealing with this and Kia’s dealer services are horrible followed along by thee corporate being terrible too”

“In April 2025 my vehicle had a recall (1: SC336 or 25V099), I brought it into a Kia dealership, they said it failed the test, and needed a new engine (i was without a vehicle for weeks, dealership said they did not have any loaners until after 14 days). They then call back weeks later saying the test was faulty, and i could have my car back. They said to keep an eye on it if there are any issues regarding the recall to come back. One morning i started my car, and was driving luckily in a 30mph, my car started to shake, would not speed up/move much, the check engine light came on, almost coming to a complete stop in the middle of a busy road. I was able to move it to the side, turn it off for a bit, once turned back on it was fine. My father who has a background in automotive mechanics checked the oil and noticed there was barely in it- (although just having it been changed) which looks like the oil consumption is fast and going somewhere. I immediately took it to a Kia dealership and they said I would have to go through a whole oil consumption test but it would not be a guarantee fix for engine replacement due to me not going to a dealership, or oil change…”

“Driver side rear door glass exploded spontaneously at 65mph for no reason, sending glass all over the interior. Was on a two lane highway in a remote area with no other traffic. Outside temperature was about 15 degrees. With no other underlying cause apparent. Stopped at the dealer immediately afterwards to have a warranty claim submitted. Kia denied the claim.”
